About five years ago my father-in-law was the victim of a scam artist who fleeced him out of £5,000. Once he realised, he was devastated and we were able to work with his bank to get some of the money back. We thought it was all in the past but in the last six months he’s received numerous calls, letters and texts from what look like other scammers. We want to try and keep him safe as his memory isn’t the best, what can we do?

Unfortunately, falling victim to a scam once can increase exposure to further scams. Citizens Advice has found that, once someone has responded to a scam, their personal details can sometimes be sold onto other criminals. This then opens the door to more scam mail, emails, phone calls or home visits.

If you recognise a pattern of unsolicited calls, talk to your father-in-law’s telephone provider and see if you can get these numbers blocked or if you can get something called a ‘standalone call blocker.’ If not, register your father-in-law’s number with the Telephone Preference Service who can help you to handle unwanted marketing calls.

If your father-in-law is receiving texts it’s important that he never replies, as sometimes there can be costly hidden charges. He can report the texts to his mobile phone provider who will be able to block the number. If he’s already been stung and call cost information wasn’t given, he should report it to Phone-pay Plus.

Mail scammers can often impersonate banks, the local council, or other established and legitimate organisations. You should advise your father-in-law against responding unless he’s sure it’s legitimate and was expecting a letter. If in doubt he should contact the organisation directly to check the letter’s legitimacy. He should be careful to not just ring up the number on the letter as it could be a bogus call centre.

In addition, to safeguard your father-on-law from unwanted marketing material or junk mail, register his name and address for free with the Mailing Preference Service which will take his name off some mailing lists.

Doorstep scammers can often be intimidating, and unfortunately they commonly target older and more vulnerable people. Your father shouldn’t be embarrassed turning people away and shouldn’t let them in unless he’s expecting them. If someone comes to the door saying they are from one of his utility companies for example, he should ask to check their credentials. If in doubt, he should phone the company they represent or check online, but once again make sure to not just use the contact details they provide.

Trust your instincts and if in any doubt, don’t part with your money. For further help on identifying possible scams contact your local Citizens Advice, or call the Citizens Advice consumer service on 0800 144 88 48.
